Abstract: 323,480. Marks, Sir G. C., (International Cigar Machinery Co.). Sept. 28, 1928. Cigar-making machines.-In a mechanism for wrapping a previously formed cigar bunch, side rollers 43, 44 and top rollers 41, 42 are carried by opposed brackets 48, 49 pivotally mounted for movement towards and away from each other on a common stationary shaft 51, so that in the operative positions of the rollers the lines of contact with a bunch of the side and top rollers carried by each bracket are equidistantly spaced from the corresponding rollers of the other bracket. As shown, the top rollers are carried by brackets 45, 46, Figs. 1, 5 and 7, held together by tie rods 47 and pivoted on the ends of the respective side rollers 43, 44, the brackets 45 being held against adjustable stop screws 55, 56 on the brackets 48, 49 by springs 53. A cam shaft 17 is driven from the main drive shaft of the machine through spur gearing 19, 20, &c. and drives the side and top rollers 41 - - 44 through change-speed gearing comprising pinions 28, 29, Fig. 2, carried by a bracket 30 and meshing with a spur gear 27 on the shaft 17. The bracket 30 is clamped to a bushing 31 of the shaft 17 with one or other of the pinions 28, 29 in mesh with a gear 33 on a stud 34, from which the rollers 41 - - 44 are driven through gearing 35, 57 - - 61. The rollers 41 - - 44 are opened and closed, for the insertion and removal of a cigar bunch, by means of adjustable rods 62, Fig. 7, secured to blocks 71, strung on tie rods 50 connecting the brackets 48, 49, and to brackets 63, 64 pivoted to a lever 66 actuated by a cam 69 on the shaft 17, means being provided for adjusting the cam accurately about the shaft. While being rolled, the cigar bunch is supported at its ends by a stationary header block 72, Fig. 10, and a tuck support consisting of conical rollers 74, Fig. 8, supported by end plates 75, 76 on a block 73 clamped to the shaft 51 by a saddle piece 77. This carries a shaft 78 on which swings an arm 79, Fig. 1, for engaging the tuck end of each incoming cigar bunch and pushing it into position before the rollers close on it. The arm 79 is actuated by a cam 88 through a lever 86 and an adjustable rod 81. During rolling, the wrapper is held against the tuck end of the bunch by a camactuated tuck needle (not shown) entering through a double-cored bushing 93. The header unit, Figs. 1 and 10, consists of an adjustable header cone 94, carried by an arm 95 clamped to a stud 96 on an arm 97, the axis of the stud 96 passing through the cigar tip. The arm 97 is resiliently pivoted on a pin extending radially from an arcuate bracket 99 sliding upon the circular face of a fixed block 102, to which it is bolted in adjusted position. An extension 105 of the arm 97 rests upon a lever 107 pivoted at 108 and actuated by a cam 111 adjustably mounted on the shaft 17. A finger 113 pivoted on the lever 107 is held by a spring 114 against a stop 115. When the finger 113 is engaged by the nose 116 of an adjustable cam 117, the lever 107 is lifted, raising the header cone 94 to make way for a flag cutter (not shown). A lever 118 for actuating the flag cutter is raised by the engagement of the arm 119 of the lever 107 with the lower stop screw 120 in the forked end of the lever 118. After the nose 116 has passed the finger 113, the cam lever 107 drops until stopped by the upper stop screw 121, causing withdrawal of the flag cutter. The impact of the finger 113 is taken by an adjustable stop 122 and the lever 107 then brings the header cone gradually into rolling position.
